Abstract

Floral diversity was determined in 12 selected cave entrances of Burdeos, Polillo Island, Quezon during both the dry and wet season. A 5x5 m quadrat was used to determine the floral composition of each cave entrances. Altogether, there were 50 species belonging to 48 genera and 31 families. The results showed that low Sorensen's Index of Similarity between the two seasons, the highest of which is in Puting Bato Cave V. The highest diversity was in Puting Bato Cave II Entrance 1 during the dry season but in Mapanghe Cave Entrance I during the wet season. The results suggest that species found in cave entrances are plants that can tolerate conditions that are otherwise unfavorable to other plants. These include ferns and succulents shrubs. Cave entrance plants are most probably affected by different factors like humidity, temperature and light intensity. In terms of cave ecology, plants in cave entrances are also sources of energy for cave-dwelling species. Hence, they are directly correlated to the communities inside caves.
